## Summary - reset the Metrics Explorer internal data-source reference when an instance switch makes the selected source unavailable - reload the selected metric through the default source immediately after fallback - cancel the scheduled fallback during effect cleanup - cover instance-scoped source fallback and subsequent refreshes with a regression test ## Root cause and impact The availability effect cleared only the rendered `dataSourceKey` state. The stable ref used by the query callback retained the previous instance's source key, so the selector appeared to use the default source while refreshes continued querying the unavailable source. Keeping the state and ref synchronized prevents cross-instance metrics requests. Closes #1603 ## Validation - npm test -- --run src/components/__tests__/MetricsExplorer.test.tsx (9 passed) - npx eslint src/components/MetricsExplorer.tsx src/components/__tests__/MetricsExplorer.test.tsx - npm run build - git diff --check -- This is an automated message from the Apache Git Service.
